Normally when this happens it's either because you're accidentially using
the old initdb due to a PATH quirk you didn't anticipate, or PGDATA is
pointing to the wrong place; maybe you set it explictly in initdb using
"-d" but it's pointing at the wrong place?
The troubleshooting path to figure out what causes this is to see if
you're getting something that still points to the old version from the
following:
echo $PGDATA
which initdb
initdb --version
which pg_ctl
pg_ctl --version
The other thing that can be helpful to confirm what is happening is to
look at the output from pg_config to see where it put everything at.

Greg,
Thanks for your feedback - those concerns are the first ones we double-tested. In fact, we've been using explicit, full-path commands specifically to preclude the possibility of a 'wrong-path' error. We do have a few PostgreSQL clusters running here, on different ports, for various testing, so we're pretty attentive to all this.
The start command we're testing with, for example (the only variable is datapath: data-NEW vs. data-OLD):
# /usr/local/postgres/8.5-alpha2/bin/pg_ctl -D /var/postgres/8.5-alpha2/ data-NEW -l /var/postgres/8.5-alpha2/TEMPLOG start
(above works great, with an alpha2-init'd data cluster)
Same command, using the alpha1 cluster - the 'OLD' cluster:
# /usr/local/postgres/8.5-alpha2/bin/pg_ctl -D /var/postgres/8.5-alpha2/ data-OLD -l /var/postgres/8.5-alpha2/TEMPLOG start
(reports: The database cluster was initialized with PG_CONTROL_VERSION 843, but the server was compiled with PG_CONTROL_VERSION 851 )
For the sake of argument, let's test the possibility I had init'd the cluster with an 8.4 initdb:
But this command - the alpha1 binary loading the 'OLD' cluster :
# /usr/local/postgres/8.5-alpha1/bin/pg_ctl -D /var/postgres/8.5-alpha2/ data-OLD -l /var/postgres/8.5-alpha2/LOULOG start
Works just fine!
$PGDATA is empty
# /usr/local/postgres/8.5-alpha2/bin/pg_ctl --version
pg_ctl (PostgreSQL) 8.5alpha2
Weird, huh?

Normally when this happens it's either because you're accidentially using
the old initdb due to a PATH quirk you didn't anticipate, or PGDATA is
pointing to the wrong place; maybe you set it explictly in initdb using
"-d" but it's pointing at the wrong place?
The troubleshooting path to figure out what causes this is to see if
you're getting something that still points to the old version from the
following:
echo $PGDATA
which initdb
initdb --version
which pg_ctl
pg_ctl --version
The other thing that can be helpful to confirm what is happening is to
look at the output from pg_config to see where it put everything at.
